Car: 94 GT Manual 300K miles

Situation: When starting the car with the engine warm, the engine will turn over and over and over without starting. If I give the car a little gas while turning over, the car will start up, and then have a rough idle for a few seconds and be fine.

The odd thing is, if I start the car using this method, turn it off, then try and start the car again immediately it will start up with no issues. If I end up leaving the car for 15-30 minutes (I've timed it) then it doesn't want to start. I don't even know where to begin with this one.... Any suggestions?

Get your battery checked and make sure your terminals aren't corroded.

you getting fuel into the engine when it won't restart?

i had this problem and well as the cold start issue...trying to remember what toyota did to resolve it

this seems to be a bug for quite a few owners. if you find anything please post it ASAP. my 99GT is also plagued with poor starts and idleing. it seems to be random and happens at temperature ranges from 0F to 90F regardless if the engine is warm or not. i have done most everything i can find in the archives and the knowledge base to cure it-- replaced battery, cleaned battery terminals, replaced distributor, replaced wires, replaced spark plugs, replaced air filter, cleaned IAC valve and even sacrificed an offering to the Dragon God...still no luck.

appreciatively,

I had this problem on and 2nd gen Ford Probe... We changed the computer and it fixed it :-/ maybe that's your problem...

do you have any codes?
btw, not every code lights the CEL

The terminals and battery are fine. The thing is that the car turns over and will keep going until I press the gas pedal... then it starts up with a crappy idle.



In all honesty, based on my limited knowledge, I would imagine it to be something fuel related seeing as when I press the pedal it starts... but I don't know. I didn't think that pressing the pedal on newer cars made a difference when the car was off.



I have no clue... every single time I have tried to pull the codes using the paperclip trick, the CEL comes on and stays on. No flashing whatsoever... Maybe I am doing it wrong.

Take the throttle body off and clean the Idle Air Control valve, see if that makes any difference. The 5SFE is known for bad IAC valves.

fuel pressure regulator!!!!

E1 & TE1?
should be the center and bottom towards you

x_x_____x_*_x

X and x = pins
* = pins you should short out to get the codes
_ of course is just blank space (we cant add more than one space in succession )

But wouldn't a bad fuel pressure regulator cause poor idle all the time when the car is running?



I will try it again tomorrow and see if I can figure it out. Thanks for the diagram.
